[Rcpp-devel] Calling ggsave or pdf from RInside

[Michael Morrison]

Thanks for your reply, much appreciated. The call works just fine if I make
it from the R GUI or R studio. I tested out the calls there first before
trying to make the same calls from RInside. Do you know if there's a way
that the base directory can be set through some other call?

Thanks,
Mike
